A hydraulic magnet for excavator is a lifting device that combines hydraulic power with vacuum suction technology. It can quickly pick up and transport flat or partially curved materials. Compared to traditional lifting methods using wire ropes or hooks, the excavator magnet attachment significantly reduces surface damage to materials while greatly improving operational efficiency. It is widely used in construction projects, steel structure fabrication, glass curtain wall installation, machinery manufacturing, shipbuilding, and warehouse logistics. This article highlights two successful case studies in Europe, Poland and Portugal.

Case Study 1: Polish Steel Structure Factory — Automated Steel Plate Handling
Client Background
A large steel structure processing company located in central Poland specializes in producing steel beams, plates, and welded components. The factory handles daily steel plates ranging from 5–20mm in thickness, including carbon steel and stainless steel. The production workflow is primarily assembly-line based, requiring frequent lifting and transporting of heavy steel plates. Previously, workers relied on wire ropes and hooks for lifting, which were inefficient, prone to surface scratches, and required multiple personnel, posing safety risks.
Challenges
- Traditional lifting methods often caused scratches and deformation on steel plates, leading to higher defect rates.
- Manual binding and hooking were time-consuming, creating delays between production stages and limiting overall capacity.
- The factory had limited personnel, and multiple operators were needed for each lifting task, increasing labor costs.
- Steel plates varied in size, and conventional clamps lacked flexibility, failing to support diverse production needs.
Solution
For this factory, we recommended the YGML06 hydraulic magnet for excavator, designed to fit 12–16-ton excavators. The magnet has a 900mm diameter, 8kW power, and matches the factory’s hydraulic flow, providing stable lifting without damaging steel surfaces.
- A sealed magnetic surface suitable for both carbon steel and stainless steel plates.
- Equipped with power-off retention and magnetic alarms, meeting EU safety standards.
- Quick-connect design allows fast attachment changes, ensuring excavator productivity is not interrupted.
- On-site calibration of magnetic strength and operator training for daily checks and maintenance.
Implementation Results
- Single steel plate lifting time reduced from 8–10 minutes to 3–4 minutes, improving handling efficiency by roughly 50%.
- Steel surfaces remained scratch-free and undamaged, reducing material waste.
- One operator could complete lifting tasks alone, saving two additional workers and cutting labor costs.
- Equipment operated stably with minimal monthly downtime; maintenance only required cleaning seals and inspecting hydraulic lines.
Client Feedback
The factory reported that the hydraulic magnet for excavator was easy, safe, and reliable. It perfectly solved the problem of scratched plates and low efficiency. The quick-switch mechanism was praised, and the customer plans to purchase more for future factory expansion.
Case Study 2: Portuguese Construction & Installation Company — Glass & Stone Installation
Client Background
A construction company in northern Portugal specializes in high-rise building glass curtain walls, and exterior stone installation. Projects are often in dense commercial areas, requiring handling of large glass panels (2.4m × 3.6m) and granite slabs. Safety and material integrity are crucial due to high elevation and limited working space.
Challenges
- Glass and stone are fragile and prone to edge chipping; traditional lifting methods led to high breakage and material loss.
- High-altitude work made manual handling risky, increasing safety concerns.
- Fast-paced curtain wall installation required tools that could match installation speed.
- Outdoor work environments demanded equipment with dustproof and rain-resistant capabilities.
Solution
For this project, the YGML04 excavator magnet was recommended, compatible with 7–11 ton excavators and featuring an 800mm diameter with even magnetic force, specifically for glass and stone handling.
- Soft sealing pads on the magnet protect fragile edges from crushing.
- Dual power-retention and anti-fall systems meet Portuguese high-altitude safety standards.
- Quick hydraulic connections allow use with small excavators in narrow urban spaces.
- Portuguese operation manual and spare parts kit provided for outdoor maintenance guidance.
Results
- Breakage rate for glass and stone has been reduced to near-zero, significantly lowering material loss.
- Single-operator remote control reduced manual support at heights, improving construction safety.
- Curtain wall installation speed improved, meeting tight project deadlines.
- Magnet sealing and hydraulic system remained stable in outdoor sunlight and humidity.
Client Feedback
The customer praised the excavator magnet attachment for smooth and precise operation, fully compliant with European high-rise installation standards. The equipment’s safety and simple maintenance helped reduce breakage and operational risks, making it a trusted tool for curtain wall projects.
Why Excavator Magnets Are Increasingly Popular
- Higher Efficiency per Operator: One excavator equipped with a hydraulic magnet for excavator can replace multiple manual workers, significantly boosting project efficiency.
- Reduced Material Loss: Magnets securely hold metal or stone materials, reducing surface scratches, breakage, and waste.
- Safety Improvement: Operators can handle heavy, fragile, or irregular materials from a safe distance, lowering workplace accidents.
- Adaptable to Multiple Materials: Modern magnets work with steel plates, glass, granite slabs, and other materials, making them versatile for construction and industrial tasks.
- Faster Project Completion: Quick attachment and release features, combined with hydraulic efficiency, shorten lifting and installation cycles, improving overall project profitability.
- Compatibility with Various Excavators: Available for mini, mid-size, and large excavators, excavator magnet attachments can be deployed across different project scales.
